Habitat suitability and potential biological corridors for waterbirds in Yancheng coastal wetland of China

Ecological Indicators, Journal Year: 2023, Volume and Issue: 148, P. 110090 - 110090

Published: March 5, 2023

Yancheng coastal wetland, as an important part of the East Asian–Australasian Flyway, provided habitat for more than 200 migratory waterbirds by rest and over-winter. After it was listed a “World Heritage List” in 2019, protection waterfowl wetland has attracted extensive attention from international community. As indicator species ecosystem health, have practical significance wetlands. Due to long-term impact human activities, waterbird habitats are facing threat fragmentation lose, posing serious challenge its survival diversity. Based on survey data obtained Gruiformes, Charadriiformes, Anseriformes during whole years 2017 2021, this paper used Maxent software modeling niches distributions, comprehensive evaluation method based fuzzy mathematics, Linkage Mapper model assess suitability distribution waterbirds, identify gaps potential biological corridors wetland. The results showed that anthropogenic disturbance were decisive factors affecting selection waterbirds. suitable 23868, 22670, 24870 ha, respectively. area 121,930 concentrated study area's central southern coast.

In order to effectively conserve a species and manage its population, it is critical understand the impact of climate change on habitat quality connectivity. The sika deer (Cervus nippon) ungulate endemic East Asia listed as Category I State Key Protected Wild Animals under Chinese law. C. nippon population was established in Shennongjia area 30 years ago, there an urgent need analyse environmental quality. this study, we compared suitable habitats connectivity by utilizing ecological niche model that integrated set factors combined with cost-distance approach for both present time well future. most encouraging findings were may be obviously enlarged improved change. limited at present; however, possible total number patches can increase twenty- thirty-fold quadruple sextuple, respectively, future (2050–2070). We detected clear trend expansion into northeast. interpatch least-cost paths dramatically (up six twelve times higher), lengths movement costs decrease half. Based these results, several conservation recommendations have been suggested. Our study provides valuable reference protective actions taken serve template establishing strategies other species.

Long‐Distance Corridors Facilitate Asian Elephant Adaptation to Climate Change

Integrative Conservation, Journal Year: 2025, Volume and Issue: unknown

Published: March 10, 2025

ABSTRACT Amid ongoing habitat degradation and fragmentation, along with the disruption of traditional moving routes, Kunming‐Montreal Global Biodiversity Framework underscores urgent need to enhance species connectivity improve their adaptability climate change. Recent instances long‐distance movements by Asian elephants ( Elephas maximus ) have raised concerns about potential for such events become more frequent under future scenarios. A landscape adaptation strategy is urgently needed integrity elephant habitats meet movement requirements. However, large‐scale ecological networks that incorporate corridors remain lacking. This study employs distribution models minimum resistance construct current multi‐scenario networks, aiming elucidate key features priority corridor strategies elephants. Our findings indicate identified scenarios play an integral part in maintaining within network. The identifies 162 corridors, accounting 25.5% overall network, whose lengths importance are expected increase. Additionally, 37.2% these pass through protected areas, providing guidance optimizing existing reserves addressing conservation gaps cover 61.2% area. highlights fully consider uncertainties dynamic spatiotemporal changes. It emphasizes global significance macro‐scale network design critical role constructing corridors. Furthermore, integration areas as a measure address achieve lasting biodiversity conservation.

Assessing human–Asiatic black bear (Ursus thibetanus) conflicts in Kumrat Valley—Western flanks of Hindu Kush Region, northern Pakistan

Global Ecology and Conservation, Journal Year: 2022, Volume and Issue: 38, P. e02230 - e02230

Published: July 14, 2022

The rapid expansion of the human population into wildlife habitats increases human-wildlife conflicts (HWC) and threatens survival dwindling populations. HWCs are a major problem globally but most prevalent in countries where part adopts agro-pastoralist life as primary source income. In Pakistan, has led to highly negative attitude towards apex predators one chief reasons for retributory killing rare carnivore species. One such involved is Asiatic black bear (Ursus thibetanus), listed vulnerable Pakistan. Surveys human-bear interactions were conducted Kumrat Valley Dir upper district, Khyber Pakhtunkhwa (KP) province. We used semi-structured questionnaire interview 104 randomly selected respondents between February-March 2022. According respondents, bears attacked 14 individual livestock over past two years, incurring an economic loss USD 2392. However, incurred higher though damages crops, causing total 7302 with annual 3651 (USD 35.1 per household). Guarding was predominant factor influencing patterns predation. Season main influence on rates crop damage, highest levels observed summer. 67.31% had wanted its elimination or reduction from area owing losses. people's attitudes influenced by four factors: education, agricultural land owned, sightings. Despite losses bears, not single been killed locals. Based findings this study, it recommended that insurance schemes damage implemented. These should be coupled effective awareness campaigns ensure maintain peaceful co-existence humans intact ecosystem.

Global warming due to anthropogenic activities has alarming effects on biodiversity. It could negatively impact the interactions between predators and their prey by shifting or eliminating suitable habitats. The predator common leopard (Panthera pardus) two species, Himalayan grey goral (Naemorhedus goral) langur (Semnopithecus ajax) play important roles in balancing forest ecosystem northern Pakistan. is listed as a Vulnerable species IUCN Red List, while are Near Threatened Endangered respectively.
